           Summary: Spurious warnings on Indexed colour spaces ?
           Product: Ghostscript
           Version: master
          Platform: PC
        OS/Version: Windows Vista
            Status: NEW
          Severity: normal
          Priority: P4
         Component: PDF Interpreter
        AssignedTo: alex.cherepanov at artifex.com

Created an attachment (id=8034)
 --> (http://bugs.ghostscript.com/attachment.cgi?id=8034)
offending file

The attached file raises a warning that the Indexed space has a short lookup
table for every Indexed space in the document.

I'm not convinced this is correct, and I'm wondering if the PDF interpreter is
getting confused by using the stream length of a compressed stream to determine
if there is sufficient data for the lookup table.

If I decompress the file suing either pdfclean or pdftk the warnings go
away....
